These were followed in the early 1950's by four different pocketbook sf
magazines which were both undistinguished and, apart for the titles,
indistinguishable. The first was Futuristic
Science Stories, which ran on an almost quarterly basis for fifteen issues
(although a sixteenth issue, with all stories written by John S. Glasby, appeared four
years after the magazine folded). This was followed, in short order, by Tales of Tomorrow, Worlds of Fantasy and Wonders of the Spaceways.

Following these, in 1954, Spencer launched two new magazines, both devoted to weird
fiction - Supernatural Stories and Out of This World. The latter only lasted
for two issues, each of which were later printed as issues of Supernatural Stories.
Supernatural Stories itself had a rather more complex history. The
first series (mainly written by John S. Glasby) ran for eight issues. There was then
a hiatus of almost two years until it was revived as one of the Badger Books paperback
lines (this time mostly written by Lionel Fanthorpe). Three of these issues were
titled Out of This World on the cover and spine, and several others
(which consisted of a single novel each) were headed Supernatural Series.
